Leduc 0.22

Development of the Leduc 0.10 continued with two examples of the larger Leduc 0.21 of improved design, the first making its initial flight on 16 May 1953. These proved to be successful, demonstrating a maximum speed of Mach 0.87 and attaining an altitude of 20,000m.

Development then began of the Leduc 0.22 Mach 2 interceptor which incorporated a SNECMA Atar turbojet within the athodyd to allow the aircraft to take off under its own power and then accelerate it to a speed at which the ramjet would ignite. This was not achieved with the 0.22, for although flown on turbojet power for the first time on 26 December 1956, and later making more than 30 test flights with the turbine engine, the ramjet was not tested. This resulted from withdrawal of government financial support, because of economic stringencies, and the project was abandoned.
